我想对 zend 框架 3 教程页面上的专辑应用程序实现进行单元测试。我在原始实现中添加了一些功能（登录和 acl）。我按照教程进行单元测试 zf3，但无法遵循它，如何模拟身份验证和编写更多测试用例。感谢任何帮助。一些代码来自我的相册应用程序实现。

ZF 有一个服务管理器，可用于依赖注入。您已经在使用它，因为您将 UserTable 和 LoginTable 注入到控制器中。将对象注入控制器和其他服务的主要原因是可重用性和可测试性。这两个注入的服务可以很容易地被模拟，并且模拟的版本可以在测试期间被注入到这些类中。

您在控制器内部或其操作中实例化的所有对象都不能被模拟。所以你想重构并取出ACL、用户会话容器和AuthenticationService。如果需要，为那些编写工厂并将它们添加到服务管理器中。最后在需要的地方将它们注入控制器。现在您可以模拟它们或为每个组件编写单独的测试。

下一个问题是在控制器内部构建查询以创建数据库连接。同样，创建数据库连接将进入工厂，因此您可以重用它并在需要的地方注入它。构建查询将进入存储库。Als 用户名和密码应该进入一个本地配置文件（一个被 git 忽略的文件）。

ZendFramework 有多个包可以帮助您：
